Reconstruction of theWanborough Plain (Phase 2) 21-07-2012 formation | |||||

1. |
Steps 1 through 25 are identical to those of the reconstruction of Wanborough Plain (phase 1) (1-07-2012). These steps are repeated here for convenience. Draw a circle. Draw and extend the horizontal and vertical centerlines. | ||||

2. |
Construct the circumscribed dodecagon (regular 12-sided polygon) of circle 1, with the mid-point of one side on the horizontal centerline (to the right). | ||||

3. |
Construct the circumscribed circle of dodecagon 2. | ||||

4. |
Construct the inscribed hexagon (regular 6-sided polygon) of circle 1, pointing up. | ||||

5. |
Construct the inscribed circle of hexagon 4. | ||||

6. |
Construct the inscribed nonagon (regular 9-sided polygon) of circle 5, pointing up. | ||||

7. |
Construct the inscribed circle of nonagon 6. | ||||

8. |
Construct the inscribed equilateral triangle of circle 1, pointing up. | ||||

9. |
Construct the inscribed equilateral triangle of circle 1, pointing down. | ||||

10. |
Construct the inscribed equilateral triangle of circle 7, pointing up. | ||||

11. |
Construct the inscribed equilateral triangle of circle 7, pointing down. | ||||

12. |
Construct a circle centered at the top of triangle 8, tangent to circle 3 at the upper side. | ||||

13. |
Copy circle 12 to the intersection of the lower side of triangle 8 and the vertical centerline. | ||||

14. |
Construct an equilateral triangle (the circumscribed circle of which is) concentric to circle 1, pointing up, and with its lower side tangent to circle 13 at the lower side. | ||||

15. |
Copy circle 12 to the intersection of the lower side of triangle 10 and the vertical centerline. | ||||

16. |
Construct an equilateral triangle (the circumscribed circle of which is) concentric to circle 1, pointing up, and with its lower side tangent to circle 15 at the upper side. | ||||

17. |
Construct a "two-points" circle (defined by the two end-points of a centerline) between the center of circle 12 and its lower intersection with the vertical centerline. | ||||

18. |
Copy circle 17 two times, to the lower angular points of triangle 8. | ||||

19. |
Copy circle 17 to the center of circle 1. | ||||

20. |
Construct three pairs of parallel lines, all tangent to circle 19, and pairwise tangent to circles 17 and 18 respectively, all at both sides. | ||||

21. |
Construct three rays of circle 1, from its center to the angular points of triangle 9. | ||||

22. |
Determine points A, B and C. A is the intersection of the lower lines 20 with the vertical centerline, B and C are the lefthand and righthand intersections of these lines and the lower side of triangle 16. Divide line AB into four equal parts, and number the nodes 1, 2, 3, from left to right. | ||||

23. |
Divide line AC into four equal parts, and number the nodes 4, 5, 6, from left to right. | ||||

24. |
Draw four connecting lines, between points B and 4, 1 and 5, 2 and 6, and 3 and C. | ||||

25. |
Repeat steps 22, 23 and 24 two times, with respect to the other two sides of triangle 16, each rotated over 120° about the center of circle 1, as shown. | ||||

26. |
Copy circle 12 to the intersection of the upper side of triangle 9 and the vertical centerline. | ||||

27. |
Construct an equilateral triangle (the circumscribed circle of which is) concentric to circle 1, pointing down, and with its upper side tangent to circle 26 at the upper side. | ||||

28. |
Copy circle 12 two times, to points B and 4. | ||||

29. |
Construct a line tangent to circles 28 at the lower sides. | ||||

30. |
Copy circle 12 two times, to points 3 and C. | ||||

31. |
Construct a line tangent to circles 30 at the lower sides. | ||||

32. |
Repeat steps 28, 29, 30 and 31 two times, with respect to the other two sides of triangle 16, each rotated over 120° about the center of circle 1, as shown. | ||||

33. |
Circles 1, 3 and 7, triangles 8, 9, 10, 11, 14, 16 and 27, and lines 20, 21, 24, 25, 29, 31 and 32, are used for the final reconstruction. | ||||

34. |
Remove all parts not visible within the formation itself. High resolution dwf-file | ||||

35. |
Colour all areas corresponding to standing... High resolution dwf-file | ||||

36. |
...or to flattened crop, and finish the reconstruction of the Wanborough Plain (Phase 2) formation of 21-07-2012. High resolution dwf-file. | ||||
